October 21 is the long-awaited Back to the Future day and this clip of the franchise's stars should make every fan's day.

Yes, Michael J. Fox and Christopher Lloyd star in what is essentially a commercial for Toyota, but one that is heavy on the film's references, not to mention locations.

The clock tower, Marty's house and his truck all make appearances, but the true stars, no doubt, are Lloyd and Fox. Frankly, we have to watch the video again to see just what the heck Toyota is hawking here because we were too busy being in our Back to the Future glory to pay much attention to the true point of the spot.

And while 2015 may not be as amazing as we'd been led to believe in Back to the Future Part II, there's no denying this reunion is one treat we didn't see coming that we are glad did come to fruition.
